1. A method for reducing a burden associated with analyzing electrogram (EGM) segments obtained from an implantable medical device (IMD) that is configured to monitor for arrhythmic episodes of a patient within which the IMD is implanted, the method comprising:
obtaining respective EGM data and respective classification data for each arrhythmic episode of a plurality of arrhythmic episodes that were detected by the IMD during a period of time, wherein the respective EGM data is indicative of an EGM segment corresponding to the arrhythmic episode, and wherein the respective classification data specifies a type of the arrhythmic episode;
obtaining a representative R-R interval or a representative heart rate (HR) for each of the arrhythmic episodes, wherein for at least two different types of the arrhythmic episodes the respective manners for determining the representative R-R interval or the representative HR differ from one another;
selecting one or more EGM segments to be displayed for each type of arrhythmic episode, of a plurality of different types of arrhythmic episodes for which the EGM data and the classification data were obtained for the period of time, the selecting based on the representative R-R intervals or the representative HRs that are determined for the plurality of arrhythmic episodes; and
providing for display of the EGM segments that correspond to the one or more arrhythmic episodes that were selected for display, for each type of arrhythmic episode, of the plurality of different types of arrhythmic episodes for which the EGM data and the classification data were obtained for the period of time;
wherein the representative R-R interval or the representative HR for each bradycardia type of arrhythmic episode, for which respective EGM data and respective classification data were obtained, comprises a longest R-R interval or a slowest HR during the bradycardia type of episode.
